Today is the equinox day, when the sun rises due east & sets due west, the setting sun's rays pass sequentially through the 5 windows/openings in the Sree Padmanabhaswamy Temple in Thiruvananthapuram, Kerala's (India)tall gopuram (entrance tower). Not a coincidence but an intentional ancient engineering tied to astronomy & precise design. The Earth rotates at a speed of approximately 0.25 degrees/min. To have the sun jump from 1 window to the next in exactly 5 mins, the vertical angle b/w each window opening must be precisely 1.25 degrees relative to a specific observation point on the ground. The architects built a Vertical Protractor. They calculated the height of the Gopuram (tower) & the distance of the viewer to ensure the frame rate of the sun matched the human sense of a significant interval (5 mins). 🙏🙏🙏🙏

@samirkseth Yes, sir, cos we have the bilateral vehicle agreement with nepal but not Sri Lanka.

@Fintech03 So apparently indian vehicles can enter Nepal without a "Carnet de Passages" - there is a different arrangement involving a fee payment of INR 250–500/day for cars.

Sir, the Palk Strait is deceptively shallow. At its shallowest point (the Ram Setu), the water is sometimes only 1-3 m deep. A true Ro-Ro car ferry, the kind that carries 100+ SUVs requires a deep draft (it sits deep in the water). A heavy car ferry would literally ground itself on the sandbars of Ram Setu. For a moment, we assume this gets taken care of. Now, to take our Indian registered car to Sri Lanka, we need a Carnet de Passages en Douane (CPD) essentially a passport for our car that requires a massive bank guarantee (often 200% of the car's value). Cos India & Sri Lanka have high import duties on vehicles, the Corrupt Use Case is too high. Authorities fear people would take a ferry & then lose the car in the other country to sell it for a profit. W/o a Bilateral Road Transport Agreement, a car ferry is economically dead on arrival.

Why do we not have a car ferry that takes us from India to Sri Lanka?

Why did TN jump 29% in 4 yrs while others plateaued? Gujarat focuses on fiber (cotton production) & Maharashtra on fashion (Mumbai headquarters), Tamil Nadu focused on the full stack. In cities like Tiruppur & Coimbatore, we can find a 10km radius that contains every single step: ginning, spinning, weaving, dyeing, & retail packing. This reduces logistics friction. A t-shirt in TN travels less than 50km from raw cotton to a finished box. In other states, the fabric often travels 100s of kms b/w specialized hubs.

🚨 Tamil Nadu surpasses Gujarat and Maharashtra to become India's top textile exporter.

How is Dhurandhar 2? Been hearing a lot, mostly from X. Spoiler alert: I watched the 1st part in bits & pieces on Netflix, & the last movie I saw in a theatre was Tanu Weds Manu. Planning to watch it next weekend, been down with a severe stomach bug since yesterday so this weekend is out of question.

Vikram K. Doraiswami, India's newly appointed Ambassador to China, adopted the Chinese name Wei Jiameng. Out of curiosity, I ended up decoding his Chinese name: Wei: This is a powerful, ancient dynastic surname (The Kingdom of Wei). It gives the Ambassador historical weight. Jia: Means to add/increase. Meng: Means alliance/covenant. By calling himself Wei Jiameng, the ambassador is publicly labeling himself as "The Great Builder of Alliances."

@Fintech03 Why not consider building a land bridge or two, A landmark that might last a very long time. Indian tarrifs have been rationalized with trade agreements elsewhere, perhaps same could happen with Sri Lankan and indian tarrifs too.

There is a super duper funny story related to this: He & Laplace put a live guinea pig inside a bucket of ice to measure how much ice melted from the animal's body heat. He proved that breathing is just a slow form of Combustion & showed that the mass of O2 a guinea pig breathes in = the mass of CO2 it breathes out + the heat generated. He proved the Law of Conservation applies to Life itself, not just chemicals in a jar.

Antoine Lavoisier formulated the law of conservation of mass, one of the foundational principles of modern chemistry. It states that: Mass is neither created nor destroyed in a chemical reaction. In other words, the total mass of the substances before a reaction is exactly equal to the total mass after the reaction. Lavoisier demonstrated this through careful experiments, especially by conducting reactions in closed systems where no matter could escape. For example, when a substance burns, it may seem like mass is lost, but in reality, the gases produced (like carbon dioxide) carry that mass away. When everything is accounted for, the mass remains constant. This idea was revolutionary because it shifted chemistry from qualitative observations to precise measurement, laying the groundwork for modern scientific methods in chemistry.

Our Govt’s Swachhata-MoHUA App already contains 1 of the largest untapped collections of real-world Indian urban imagery anywhere. Every time a citizen uploads a geo-tagged photo of a pothole/garbage dump/unclean street/toilet & every time a municipal officer uploads the after photo showing resolution, the app accumulates timestamped visual pairs capturing Indian urban decay versus repair. With 5M+ downloads on Google Play, coverage across 4900+ towns & cities, & millions of resolved complaints (historical figures include nearly 1.79 cr complaints & high resolution rates like 91% in past reports), the total photos likely run into tens of millions cumulatively. Now, here is the opportunity (& I am confused why govt does not leverage it yet): The Govt does not need to build a new platform. It can convert the existing Swachhata-MoHUA photo corpus into a high value, India-specific AI-training dataset, anonymized, labeled (decay vs. repair), & structured for training computer-vision models on: - pothole & garbage detection - automated resolution verification - predictive hotspot mapping - street-level urban quality assessment This would be far more grounded & locally relevant than most globally scraped image datasets, yet the dataset remains largely unpromoted & under-leveraged beyond complaint redressal (no public evidence of large-scale AI training use currently). Additionally, API-ify the app (with strong privacy controls) so developers, startups, researchers & AI companies can access the data. Add a simple gamification layer: award verifiable cleanliness points for uploads & resolutions. Allow users to trade those points for real economic incentives: UPI cashback, Metro ride credits, partner discounts (fuel, food delivery, etc.). This turns a grievance tool into a nationwide civic + economic engine: citizens get rewarded, data quality improves through more participation, cities get cleaner faster, & India gains a powerful localized visual AI asset all w/o starting from scratch.

Sir is fine. Madam would be antithesis to my gender ;) Buttermilk is best but because buttermilk has a single or few strains, I mix it with probiotics that go well with stomach acids to fight off bugs and build better immunity for future.. you are a savant you know it all well but just my 2 cents.

Why can BYD do this when others struggle a little? It is about the Semiconductors. Standard chargers use Silicon chips. BYD is 1 of the world’s largest producers of Silicon Carbide (SiC) chips. SiC can handle voltages up to 800V/1200V with low energy loss as heat. India is also catching up in SiC space (a few companies solving this for Indian EV ecosystem): CDIL (Continental Device India Ltd.) - India's 1st company to start SiC production. RIR Power Electronics - Launched 1200V SiC MOSFETs & MPS diodes in this month only. Building India's pioneering SiC manufacturing campus in Odisha with high-voltage devices up to 20kV. Vertically integrated approach, similar to BYD's model. SiCSem Pvt Ltd. - Setting up India's 1st fully integrated SiC compound semiconductor fab in Odisha. L&T Semiconductor Technologies (LTSCT) - Partnered with Taiwan's Hon Young (Foxconn subsidiary) in 2025 to develop 650-3300V SiC wafers for EV onboard chargers, DC fast-charging stations, traction inverters, & more.

BYD’s new "gas station" that can charge an electric car from 10% to 70% in just 5 minutes.🚗⚡ At a time when energy has never been more precious, this is truly electrifying news. 🌍🌱

Sir, when we invert a potted plant, gravity now pulls in the wrong direction relative to the plant's current orientation. Statoliths immediately sink to the new bottom of the cells which is now the side that was previously the top. This triggers auxin redistribution & negative gravitropism kicks in.

I had the exact same thought while growing up & then I found out that plants actually feel gravity better than we do. Inside the tips of roots & shoots are specialized cells called Statocytes. These cells contain tiny, heavy starch grains called Statoliths. Cos they are denser than the surrounding fluid, they literally sink to the bottom of the cell. The plant doe not guess where down is; it has a physical inclinometer in every growing tip. In the roots, this signal triggers growth toward the weight (Positive Geotropism). In the stem, it triggers a hormone called Auxin to accumulate on the bottom side, causing those cells to grow faster & push the plant upward, away from the weight (Negative Geotropism).

@Fintech03 Have not watched it. Someone I know who watched the first one thrice said that this one is slow and feels like a drag plus unwanted violence. A cousin who watched the first part and felt it was just about a one-time watch is raving about the second part and will watch again.
